“And Moses spake unto the people, saying, Arm some of yourselves unto the war, and let them go against the Midianites, and avenge the LORD of Midian.”
King James Version (KJV)
31:3 Avenge ye the Lord - For the affront which they offered to God, by their own idolatry and lewdness, and by seducing God's people into rebellion against him. God's great care was to avenge the Israelites, #Nu 31:2|, and Moses's chief desire was to avenge God rather than himself or the people.
